Answer 1

You can exclude using class names like this:

"aoColumnDefs": [{ "mColumns": false, "aTargets": ["no-export"] }],

Here is similar code I have working in production:

            var oTable = $('#<%= gvComputers.ClientID %>').dataTable({
            "bJQueryUI": true,
            "bStateSave": true,
            "sPaginationType": "full_numbers",
            "aLengthMenu": [[5, 10, 25, 50, 100, -1], [5, 10, 25, 50, 100, "All"]],
            "aoColumnDefs": [
                { "sSortDataType": "dom-text", "aTargets": ["text-sort_fixed"] },
                { "sType": "numeric", "aTargets": ["numeric-sort"] },
                { "sSortDataType": "dom-select", "aTargets": ["select-sort"] },
                { "sSortDataType": "dom-checkbox", "aTargets": ["checkbox-sort"] },
                { "bSearchable": false, "aTargets": ["no-search"] },
                { "bSortable": false, "aTargets": ["no-sort"] }
            ]
        });

I set the classes as needed on my table header, footer and cells dynamically since I do not know what columns the user will remove from their personal view of the data.

Just for googlers: in tabletools 2.2.3 you can now use function for mColumns

var dataTable = $grdData.DataTable({
     tableTools: {
          aButtons: [{
              "sExtends": "csv",
              "sButtonText": "csv",
              "mColumns": function ( dtSettings ) {
                   var api = new $.fn.dataTable.Api( dtSettings );

                   return api.columns(":not(:last)").indexes().toArray();
              }
          }]
     }
});

The best I've found so far is these hacks. Not particularly useful in my case, but maybe you have better luck

Answer 4

In my case the best solution was to set the exportable attribute of the column to false. The same way you can set orderable, searchable, etc.

Answer 5

Suppose you have six columns, and you only want to display columns 1, 2, 3 and 5. Try this :

{
   text: "print",
   extend: "print",
   className: "btn btn-lg btn-danger",
   exportOptions:
     {
       columns: [0,1,2,4]}
     }
}
